We did the following upgrades:
Nintex workflow 220.127.116.11 to Nintex workflow 18.104.22.168
Nintex form 22.214.171.124 to Nintex form 126.96.36.199
and we followed all upgrade instructions but we have the following problem:
All old running workflows are stuck, if someone answered a task the workflow does not continue to next task.
After investigating the problems, it seems all workflows that contain loops or state machine has this problem, so the workflows are stuck in their loops without showing any error or proceeding to next tasks
Thank you for your help.
